In these applications, this type DCT11 Float Level Control Valve ensures precise fluid control, maintains excellent sealing integrity, and supports efficient, safe operation even under demanding conditions.
The DCT11 Float Level Control Valve is a sophisticated, hydraulically-operated valve specifically engineered to automatically maintain a preset fluid level in reservoirs, storage tanks, and towers. Designed to meet the stringent demands of modern infrastructure, this specialized valve ensures consistent inventory management, minimizes water loss from overflow, and controls the flow rate to prevent damaging surges during filling cycles.
At the core of the DCT11 Float Level Control Valve is its diaphragm-actuated main valve controlled by an external pilot system and an adjustable float. The pilot mechanism senses the fluid level via the float and modulates the main valve opening accordingly. As the level approaches the set point, the main valve closes smoothly and proportionally, providing reliable and precise control over the flow entering the storage facility.
Manufactured from high-strength, corrosion-resistant materials (such as ductile iron) and built with a robust, globe-style body, the DCT11 Float Level Control Valve is designed to withstand continuous system pressure and dynamic operational forces. Its design ensures stable modulation near the seating area, effectively mitigating the destructive effects of turbulence and vibration that can occur during partial opening.
The DCT11 Float Level Control Valve is ideally suited for applications in municipal water storage tanks, elevated water towers, industrial cooling reservoirs, and any system where accurate and reliable automatic level management is essential for operational security and water conservation. Its superior proportional control and dependable operation make it a preferred choice for engineers seeking a high-integrity, standards-compliant solution for long-term inventory and network stability.
In summary, the DCT11 Float Level Control Valve offers an optimal combination of hydraulic stability, accurate level control, and robust overflow protection. With its pilot-operated mechanism, durable construction, and focus on steady proportional flow, this unit stands as a trusted solution for modern fluid control and water storage management requirements worldwide.
1. General Information
The DCT11 Float Level Control Valve is designed for the accurate, automatic regulation of fluid level in storage vessels. Proper installation, including correct placement of the float assembly, is essential to guarantee safe operation, long service life, and efficient reservoir management.
2. Safety Precautions
Installation must be performed by qualified personnel only.
Ensure strict compliance with all local safety regulations and standards concerning working with pressurized pipelines and fluid storage facilities.
Wear appropriate personal protective equipment (PPE).
Confirm that the pipeline section feeding the reservoir is fully depressurized, isolated, and drained before attempting to install the DCT11 Float Level Control Valve.
3. Pre-Installation Checklist
Inspect the DCT11 Float Level Control Valve for any visible damage during transport or storage, paying attention to the main diaphragm housing, pilot tubing, and external float arm integrity.
Check that the valve type, size, and pressure rating match the system requirements.
Verify that the valve interior and pilot line strainers are clean and free from debris.
Confirm that the mating pipeline flanges are properly aligned (parallel and concentric) and free from burrs or sharp edges.
Ensure the float assembly is correctly mounted at the reservoir level and the connection line is secured.
4. Installation Procedure
Positioning: Install the DCT11 Float Level Control Valve ensuring the flow direction adheres to the arrow cast on the body.
The main valve is typically installed outside the reservoir, with the float pilot connected via a tube to the water level.
Use the appropriate gaskets suitable for the medium and operating conditions.
Align the valve precisely between the pipeline flanges and insert bolts, tightening them gradually and crosswise in incremental steps.
Connect the float pilot tube securely to the main valve and ensure the float mechanism is set to the desired maximum level.
5. Post-Installation
Slowly open the upstream isolation valve to reintroduce fluid and pressurize the system, checking immediately for leaks around the flange connections and the pilot tubing.
If leakage is detected, depressurize the system immediately and re-tighten the bolts or connections following the cross-pattern sequence.
Verify the float assembly adjustment and confirm the valve closes completely when the water level reaches the set point.
Record the installation details, set level, and final notes for documentation purposes.
Proper maintenance extends the service life of the DCT11 Float Level Control Valve and ensures continuous, accurate reservoir level regulation. Follow the guidelines below to maximize the longevity of this essential unit.
1. Routine Operation
Visually inspect the DCT11 Float Level Control Valve exterior, pilot line tubing, and float assembly regularly (e.g., monthly) for signs of external leakage, vibration, or fouling.
Monitor the reservoir level closely to confirm that the set point is being maintained accurately and the valve is not causing overflow.
2. Inspection Schedule
Monthly, check the pilot system strainers and filters (if present) for fouling and clean them to ensure accurate pressure sensing.
Quarterly, check the function of the main valve by manually testing the float movement and monitoring its corresponding opening and closing stroke.
Annually, perform a detailed internal inspection by removing the main cover to check the condition of the diaphragm, seating surface, and stem seals for wear or pitting.
3. Lubrication
The DCT11 Float Level Control Valve typically utilizes fluid-lubricated internal parts (water).
The float linkage pivot points may require periodic lubrication; use only recommended water-safe grease types.
4. Seal and Gasket Replacement
Replace the main cover/diaphragm gasket and pilot tubing seals immediately if external leakage is observed.
The main valve seat and disc seals should be replaced if the level cannot be maintained (i.e., the valve leaks through when attempting to close).
Always isolate the valve and fully depressurize and drain the line before attempting any maintenance work requiring cover removal.
5. Cleaning
Keep the exterior of the DCT11 Float Level Control Valve clean to prevent surface corrosion.
If the valve is disassembled, clean all internal guiding surfaces and the pilot line components carefully to ensure precision hydraulic response.
6. Storage and Spare Parts
Store spare parts (diaphragms, pilot kits, gaskets) in a dry, clean, and cool environment, away from direct sunlight and temperature extremes.
Maintain a detailed record of all inspections, level checks, and repairs performed on the DCT11 Float Level Control Valve unit.

Frequently Asked Questions about the DCT11?
What are the main advantages of this valve?
The DCT11 Float Level Control Valve provides fully automatic, highly precise level control, eliminating manual supervision and preventing costly water loss due to overflows in tanks and reservoirs, thereby protecting the storage asset.
Why should I choose this product?
This valve delivers outstanding performance in both sealing and durability, making it a dependable choice for demanding applications. Its straightforward design facilitates easy installation, offering flexibility during system design. With a wide range of material options, it meets the needs of various infrastructure projects, from municipal water networks to industrial facilities.
What is the role of the float assembly in the DCT11 Float Level Control Valve?
The float assembly acts as the sensing element; it mechanically measures the fluid level and transmits a hydraulic signal via the pilot tube to the main valve, telling the main valve how much to open or close to maintain the preset level.
Can the DCT11 Float Level Control Valve be adjusted to different water levels?
Yes. The external float assembly includes an adjustment feature that allows the user to easily calibrate the desired maximum water level set point without altering the internal main valve mechanism.
How does the DCT11 Float Level Control Valve prevent surge (water hammer) during closure?
The pilot system ensures that the main valve closes gradually and proportionally as the set level is approached, preventing the sudden stop of flow that typically causes damaging surge (water hammer) in the supply pipeline.
